Your electric drill rotates initially at 5.35 rad/s. You slide the speed control and cause the drill to undergo constant angular acceleration of 0.331 rad/s2 for 4.81 s. What is the drill's angular displacement during that time interval?

The  angular displacement  is  

Explanation:

From the question we are told that

     The initial angular speed is  

      The angular acceleration is  

      The time take is  

Generally the angular displacement is mathematically represented as

substituting values

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
